ABSTRACT:
A 90 degree swivel coupling formed of a general purpose and heat-stabilized injection molding grade 6/6 type plastic resin includes a socket member and a stem member in telescoped relation. The socket member includes an outer skirt connected by spaced flexing arms to a connecting body portion. The skirt and opposed stem have a close complementing and mating bearing projection and recess establishing a swivel coupling. The bearing walls are inclined at an angle of 15 degrees. The skirt portion is slightly expandable outwardly. In the unstressed state, the bearing wall has a maximum diameter slightly less than that of the recess to establish a pressurized fit. The stem includes a cam having an inclined wall corresponding to the bearing projection with a maximum diameter slightly greater than the bearing wall of the skirt bearing and the same angle. The cam has a maximum smaller diameter than mating recesses in the flexing arms to allow the pressure bearing engagement. The inner end of the stem and socket include an inner cylindrical and mating sections. An O-ring seal within the cylindrical sections create a fluid pressure tight coupling.
